SLIVER-CONDENSER FOR CARDING-MACHINES.

Specification of Letters Patent.

Patented Aug. 8, 1905.

Application filed February 2, 1905. Serial No. 243,877

To atl whom it may concern:

Be it known that 1, JOHN FLoRnNoE, a citizen of the United States,residing at Charlotte, in the county of Mecklenburg and State of NorthCarolina, have invented certain new and useful Improvements inSliver-Condensers for Carding-Machines, of which the following is aspecification.

This invention relates to carding-machines, and pertains especially toan attachment for such machines as are capable of working or cardingjute.

The object of the invention is to provide cardingmachines with novel andpeculiar means for receiving the material from the dofi'er and forcompressing, finishing, and shaping such material into strips, strands,or rovings.

A further object of the invention is to pro- Vide means of attachment tothe ordinary carding-machine whereby such machines are made speciallyadaptable for taking jute or similar material directly froma doifer forcompress ing, shaping, and finishing the same into separate strings,strips, or rovings without further treatment to effect this result.

A still further object of the invention is to provide a series ofgroovedrollers, a series of rotary disks working in the grooves, and loosejournal-bearings for the disks whereby the latter are given a variablebearing with respect to the rollers and effect a uniform compression ofthe material between the disks and the bottom of the grooves.

Astill further object of the invention is to provide, in acarding-machine, pairs of independent brackets in which a shaft isjournaled having a series of grooved rollers secured thereto, a pair ofloose bearings carried by each pair of brackets, a series of shaftsindependently journaled in said bearings, and a series of chutes toconvey the carded material into the said grooves for shaping andfinishing it into strips or rovings.

It has been found that in the treatment of jute, and particularly toutilize worn-out or partly-worn jute articles such as sacks, bags, andwrappings the usual mechanism for re ceiving the jute from the doffer ofthe first carding-machine and carryingit to the finisher the latter andsaid mechanism may all be dispensed with and the desired resultsattained by the application of the mechanism hereinbefore referred toand which will be hereinafter described in detail.

With these and various other objects, advantages, and improved resultsin view the invention consists in the novel construction and arrangementof parts, and particularly in combining with an ordinary carding-machinea series of rotary disks having variable bearings with respect to aseries of grooved rollers for compressing, shaping, and finishing juteor like material into strands or strips.

Difiiculty has'been experienced in forming strands, strips, or rovingsof jute and like material in machines of this character owing to theabsence of means for compressing and forming the material intocontinuous separate strands or ropes without having the compressor andformer choke for want of facilities to permit foreign matter containedin the strands to pass through the compressor.

It is therefore the purpose of this invention to obviate such difficultyand to overcome various other disadvantages found in such machines.

In the accompanying drawings, forming part of'this application, Figure 1is a side view of a carding-machine frame and dotfer, partly brokenaway, showing the application of the invention. Fig. 2 is a frontelevation, partly broken away. Fig. 3 is a sectional View on the line a:m, Fig. 2. Fig. 4 is a detail front elevation of a pair of bracketscarrying a disk, a roller, and gear. Fig. 5 is a top view of themechanism shown in Fig. 4:. Fig. 6 is a detail end view of a disk and aroller. Fig. 7 is a perspective view of one of the brackets. Fig. 8 is adetail side elevation of a pair of loose bearings carrying a disk andits shaft. Fig. 9 is a perspective view of one of the loose bearings.

The same numeral-references denote the same parts throughout the severalviews of the drawings.

The dofier 1 is driven in the usual or any suitable manner, beingprovided with an ordinary comb 2, and the frame 3 has uprights 4, towhich is secured a base 5, supporting a series of journal-brackets 6,secured thereto in pairs. A shaft 7 extends through all the hangers,having motion imparted to it by suitable means, and on said shaft withineach pair of hangers is a roller 8, having an annular groove 9, and onone side of each pair of hangers is a gear 10, secured to the shaft 7.The top of the brackets have a U-shaped opening 11, in which is fittedloose bearing-blocks 12 for a series of shafts 13, revolved in saidblocks between each pair of brackets by a pinion 14: on each shaft 13meshing with the gears 10. Secured to each of the shafts 13 between theblocks 12 is a rotary disk 15,

working in the roller-grooves 9, whereby the bearing-blocks are heldagainst longitudinal movement. In order to permit vertical movement ofthe blocks 12 and a flexible action of the disks in the grooves, a rod16 is hung from a notch 17 in the blocks and carries such Weights 18 asmay be found necessary for the proper operation of the disks.

A series of chutes 19 (one for each roller) incline from the dofierunder the comb, whence they carry the material into the roller grooves9. These chutes are suspended by a bar 20, which is supported by arms 21from the framebase. Each roller has a guard 22 projecting into theroller-grooves to prevent the material under treatment from encirclingthe groove and to keep the latter clean. It is obvious that the chutesseparate and carry the jute or similar material into the rollergroovesand under the disks, where it is compressed, shaped, and finished in itspassage between the grooves and disks into uniform strands, strips, orrovings, and that the vertical movement of the disks independent one ofthe other will permit the passage of such foreign matter incapable ofbeing compressed by the disks and rollers as may occur in the strands orstrips without choking the grooves, breaking the strips, or stopping therevolution of the disks and rollers.

It will be seen that owing to the independence of the rollers, andparticularly of the disks, each of the latter has an independentrelation to the rollers, so that either may be adjusted longitudinally,and in operation one or more disks may move vertically without suchmovement being imparted to the remaining disks.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is

1. An attachment for carding machines comprising a single shaft ofgrooved rollers in alinement, independent disk-shafts, and rotary disksworking in the grooves to compress, shape-and finish the discharge fromthe machine into a series of separate strips or rovings.

2. The combination, with a dofi'er, of a series grooved rollerspositioned relative to the doifer to have the latter discharge into thegrooves, and a series of rotary disks journaled to have a variablebearing with respect to the rollers and working in the grooves tocompress, shape and finish such discharge into a series of strips orrovings.

3. In a carding-machine, the combination of a device for compressing,shaping and finishing, comprising grooved rollers, a series of rotarydisks Working in the grooves. and means for connecting the disks androllers to permit passage therebetween of the discharge in various sizefrom the machine into separate strips or rovings of equal size.

4. The combination. With the grooved rollers having stationaryjournal-bearings, and the rotary disks working in the grooves, of meansfor loosely connecting the disks with the rollers comprising movablejournal-bearings for the disks, and weights to govern the action of themovable bearings.

5. The combination, with the grooved rollers having stationaryjournal-bearings, and the rotary disks working in the grooves, of themovable journal-bearings for the disks, and means to control the actionof the movable bearings.

6. The combination, with the grooved rollers having stationaryjournal-bearings, and the rotary disks, of the loose disk-bearings heldagainst longitudinal movement by the disks working in the grooves, andmeans to control the vertical movement of the diskbearings.

7. The combination, with the grooved rollers mounted on a single shaft,and the rotary disks each having aseparate shaft in alinement one withthe other, of a pair of brackets for each disk, and a pair ofvertically-movable journal-bearings carried by the brackets and heldagainst longitudinal movement by the disks working in the grooves.

8. The combination, with a dofier, the grooved rollers, and the disksworking in the grooves, of a chute for each disk inclined from thedoffer to carry material into the grooves, substantially as and for thepurpose set forth.

9. The combination, with a carding-machine having a suitable dofi'er, ofa series of chutes distributed throughout the length of the doffer andreceiving therefrom, a series of independent rotary disks hung in frontof the chutes, aseries of independent rollers having a groove receivingfrom the chutes and in which grooves the disks work, a pinion for eachdisk, a gear for each roller to mesh with the pinions to impart motionto the disks, a rollershaft, and means to drive the shaft.

In witness whereof I hereunto set my hand in the presence of twowitnesses.
